J. w; BALDWIN 2,347,390 HAND BEADING TOOL Filed May 6, 1943 -"j 2 v Inventor Y -E7mnz8WBaZzwzm Patented Apr. 25, 1944 UNITED STATES PATENT OFFICE HAND BEIADING TOOL Johnnie W. Baldwin, Navy Yard, s; o. Application May 6, 1943, Serial No. 485,917

2 Claims.

My invention relates to improvements in hand tools for beading sheet metal, and is designed with the primary object in view of providing a simply constructed, pliers-type, crimping tool adapted for easy operation by one man to form a bead in sheet metal along regular, or irregular, lines, and to obviate the use of the usual beading block, hammer, and round stock commonly resorted to in sheet metal beading and necessitating an extra man for holding the sheet metal in place on the block.

To the accomplishment of the above, and subordinate objects presently appearing, the preferred embodiment of my invention has been illustrated in the accompanying drawing, set forth in detail in the succeeding description and defined in the claims appended hereto.

In said drawing:

Figure 1 is a view in side elevation of my improved tool in the preferred embodiment thereof,

Figure 2 is a view in end elevation looking at the front end of the tool, and drawn to an enlarged scale, and

Figure 3 is a view in transverse section taken on the line 3-3 of Figure 1 and drawn to an enlarged scale.

Reference being had to the drawing by numerals, my improved tool comprises a pair of crossed, hand grip levers I, 2 having flattened, env larged, front end portions 3 pivoted together, as at d, and terminating in a pair of flattened front end jaws 5, 6 opposed edgewise, and extending from the portions 3 at an obtuse angle, preferably. The jaws 5, 6 are adapted to be opened and closed by movement of the hand levers l, 2 from and toward each other, respectively, as in the usual pliers.

Extending transversely of the inner edge of the jaw 5, in the transverse center thereof, and seated in a notch 6 in said edge is a round male beading die I of rod-like form detachably secured in its transverse center to said edge of the jaw by a screw 8 the head of which is countersunk in said die.

A transversely concavo-convex female crimping die 9 extends across the inner edge of the jaw 6 in the transverse center thereof and opposite the die 1 and which is detachably secured to said inner edge by a screw l passing through the transverse center of the die 9 into said jaw 6 with its head countersunk in said die 9. The die 9 is co-extensive in length with the die 1 and the latter is dimensioned to fit in said die I under closing movement of the jaws 5, 6.

A fiat gauge lug II is welded at one edge, as at [2 onto the inner edge of the jaw 6 immediately in the rear of the female die 9 to extend perpendicularly from said edge and at a right angle to the jaw and parallel with the dies 1, 9.

The nose of the jaw 5 is provided with a fiat, bar-like grip l3 welded thereto as at M, and extending across the inner edge of the jaw to clampingly engage the inner edge of the nose l5 of the jaw 6 flatwise in front of the dies .1, 9. i

In using the described tool, to head sheet metal, the edge of the sheet (not shown) is inserted between the jaws 5, 6 against the gaug lug I I. Under closing of the jaws 5, 6, the work sheet adjacent its edge will be compressed between the dies 1, 9 to form a channel-type bead in the same in a manner which will be clear. The bead may be extended along the sheet by repeat operation of the tool along the sheet. As the dies 1, 9 crimp and bead the sheet, the grip l3 co-acts with the nose l5 of the jaw 6 to loosely grip the sheet therebetween and prevent the sheet from bending in the rear of the bead.

The foregoing will, it is believed, suffice to impart a clear understanding of my invention without further explanation.

Manifestly the invention, as described, is susceptible of modification without departing from the inventive concept, and right is herein reserved to such modifications as fall within the scope of the appended claims.

What I claim is:

1. In a tool of the class described, a pair of hand levers terminating in a pair of opposed jaws and pivoted together in crossed relation for closing and opening of the jaws under movement of said levers toward and from each other respectively, a. round rod-like male die extending across the inner face of one jaw and secured thereto to extend equi-distantly upon opposite sides of said jaw, an elongated concavo-convex female die extending across the inner face of the other jaw and fixed thereto to receive the male die therein, and a, stop 7 extending from the inner face of said other jaw perpendicularly between the female die and said pivot.

2. In a tool of the class described, a pair of hand levers terminating in a pair of opposed jaws and pivoted together in crossed relation for closing and opening of the jaws under movement of said levers toward and from each other respectively, a round rod-like male die extending across the inner face of one jaw and secured thereto to extend equi-distantly upon opposite sides of said jaw, an elongated concavo-convex female die extending across the inner face of the other jaw and fixed thereto to receive the male die therein, a stop extending from the inner face of said other jaw perpendicularly between the female die and said pivot, and a flat bar-like grip extendin across the inner face of the said on jaw in front of the male die for co-action with the inner face of the other jaw in front of the female die.
